SANGERVILLE, Maine — Several members of the state police dive team spent much of Thursday searching for evidence along the swampy shore and murky depths of Carleton Stream in Sangerville.

Part of the stream runs parallel to Route 23 across from the home of James Stile, 55, who was arrested last month in connection with the Sept. 12 armed robbery of the E. W. Moore Pharmacy on Main Street in Bingham.

Stile allegedly entered the pharmacy at about 5:20 p.m. wearing a mask, ball cap and sunglasses and armed with a gun. Once inside, he demanded prescription drugs and cash, according to Lt. Carl Gottardi II of the Somerset County Sheriff’s Department. Stile ordered the four employees and a patron who were inside the pharmacy to get on the floor and then he bound their hands, Gottardi said. No one was hurt.

Piscataquis and Somerset County deputies, aided by the Maine State Police Tactical team, searched Stile’s home the day after the robbery and found 152 marijuana plants, drug paraphernalia, and cultivation equipment. A 1996 bluish-green Ford Windstar and an all-terrain vehicle were impounded but it is unknown what other evidence was seized as part of the robbery investigation. A second search was conducted at the home a few days later.

Stile was taken into custody without incident after the first search and was charged with Class A robbery. His bail was set at $250,000 cash or $500,000 single surety. He is currently being held at the Somerset County Jail.

Gottardi declined Thursday to say what police were searching for, specifically, on Thursday. Instead, he said the searchers were looking for any possible evidence related to the robbery. Federal authorities are also investigating the robbery.
